What "day" means in Genesis 1
The claim
The Hebrew word yom does not have to mean a 24-hour day. Scripture sometimes uses it for a long or indefinite period, so the six days could be ages.
Robert Sungenis holds that yom, in the singular, has only one meaning: a literal day. It appears more than 1,500 times in the Hebrew Bible, and not one of those uses is clearly figurative. Even a verse like Psalm 37:13, "he sees that his day is coming", points to one real day on which judgment begins. Only the plural, yomim, "days", can cover a longer span, as in "all the days of your life" (Gn 3:14), and even then it counts literal days.
The phrase beyom, "in the day", appears 524 times in the Old Testament and always means a single day. The one disputed case, Genesis 2:4, "in the day that the Lord God made the earth and the heavens", comes right after Genesis 2:2 uses the same word for the seventh day, and no passage anywhere calls the whole of creation one day. Genesis 1 then defines the day itself six times: "evening and morning", a period of darkness and a period of light. Christ counted twelve hours of daylight (Jn 11:9), so the full day is twenty-four hours.
“But since none of the over 1,500 appearances of the word Yom in the Hebrew bible unambiguously use it in a non-literal manner, we can safely posit that its use in Genesis 1 is literal.”
Questions on the six days of creation“This sampling shows that the Hebrew BEYOM refers to a single day, not to a conglomeration of indefinite days or an era of indefinite time.”
